I remain stumped here.  The sending host, the LAN's DNS server and the
LAN's mail hub all have forward and reverse DNS entries.  It's not at
all clear to me what sendmail is complaining about.

I had hoped to give sendmail another try after many years, but in
desperation I am compiling qmail as I type this...  :-)
